To W. H. Harvey [20–4 September 1860]
Summary
Replies to WHH’s criticisms of the Origin. Is disappointed that WHH does not understand what CD means by natural selection. CD has said "ad nauseam" that selection can do nothing without previous variability. Natural selection accumulates successive variations in any profitable direction. If CD had to rewrite his book he would use "natural preservation" rather than selection. Defends his necessarily conjectural illustrations. Agrees with what WHH says on the antiquity of the world, but it makes no impression on him. Considers the difficulty of the first modification of the first protozoan. Emphasises that there is nothing in his theory "necessitating in each case progression of acquisition", nor is it the case that "a low form would never conquer a high" in the struggle for life. Attempts to explain what he means by a "dominant" group; dominance is always relative, and he does not believe any one group could be predominant. He has no objections to "sudden jumps"; they would aid him in some cases, but he has found no evidence to make him believe in them and a good deal pointing the other way.
